Proposal for adding O_DIRECT support into JDK 9

[Lu, Yingqi]

Hi Brian,

Our email crossed :)

I used a VERY simple way to test. I removed the all the dependencies to jdk.test.lib.Platform so that I can compile and run it independently. Then, I just compiled DirectIOTest.java use the following script to test.

#!/bin/bash

for i in {1..200000}
do
    echo $i
    java -Djava.library.path=/home/JDK9-O_DIRECT/jdk10-o_direct-v15/build/linux-x86_64-normal-server-release/support/test/jdk/jtreg/native/lib DirectIOTest
done

exit 0

Since I just sent a newer version of the patch, could you please use that for testing? Please let me know if you have any question.

Thanks,
Lucy

Hi Lucy,

Do you have a wrapper script or something that you use to iterate over the test?

Thanks,

Brian

I will remove MacOS from this test for now. Could you please help test DirectIOTest on Solaris for many iterations? My VM crashed and it will take me some time to recover.
